6 Claims.

' The present invention, relates to improvements in smoking pipes and more particularly to a modified mouthpiece and stem structure therefor.

The primary object of the invention, is to provide a smoking pipe whichis rugged in construction and composed of comparatively few breakable parts to prolong the life of the smoking pipe and prevent accidental breakage of the bowl and stem through strains or shocks when the pipe is carried in the pocket.

Another object of the invention, is to provide a smoking pipe of the above mentioned character, in which the smoke passage may be controlled to facilitate regulation of the volume of smoke passing from the bowl to the mouthpiece.

Another object of the invention, is to provide a smoking pipe as above set forth in which the mouthpiece is provided with an efongate tubular member having a perforated end projecting into the bottom of the bowl of the pipe in such a manner as to prevent clogging of the smoke passageway therein by tightly packed tobacco, and to enable the elongate tubular member to be given a partial rotation to free said perforations of any tobacco particles finding their way therein.

Another object of the invention, is to provide a smoking pipe of the above mentioned character, in which the elongate tubular element is formed of metal and is positioned in the bottom ofthe bowl in such a manner as to prevent burning out of the bottom wall of said bowl by excessive heat created through the burning tobacco.

Another object of the invention, is to provide a smoking pipe in which the stem of thebowl and mouthpiece are connected by a ferrule member carried by the mouthpiece and snugly fitting a thimble on the bowl stem, so as to allow partial rotation of the mouthpiece and elongate tubular member when freeing the apertures therein of tobacco particles and, at the same time, reinforce the connection so that the joint will be strengthened and made substantially rigid.

Another object of the invention, is to provide a smoking pipe in which the elongate tubular element carried by the mouthpiece is provided with a tapered end portion having a smoke passageway or port which is adapted to be regulated by being moved into and out of a tapered recess in the wall of the smoking pipe bowl, sliding movement of the ferrule and thimble connection being relied upon to facilitate the in and out movement of end of said elongate tubular member with the smoke passageway regulating recess in the wall of the smoking pipe.

Another object of the invention, is to provide a smoking pipe'of the above mentioned character in which the ferrule connecting the stem and mouthpiece is provided with a series of heat dissipating fins to facilitate cooling of the smoke drawn through the stem and mouthpiece from the bowl during use by a smoker.

Generazgdsription of the inventionL The invention, broadly comprises a smoking pipe having a bowl with a tobacco receiving bore and a tubular stern portion in communication with said bore for'the'passage of smoke therethrough. The mouthpiece is provided with 'an elongate metal tube adapted to be inserted 'in said stem so that the perforated end of the metal tube will be disposed in the bottom portion of the tobacco receiving bore. A recess is formed in the wall of the tobacco receiving bore 'in alignment with the end of said elongate metal tube to receive the same, and thereby vary the smoke passageway therebetween when the mouthpiece is moved inwardly or outwardly with respect'to the bowl or stem projecting therefrom. Further, the invention contemplates a ferrule and thimble connection between the stem and mouthpiece to form 'a snug fitting joint or connection between the same so that partial rotation of the mouthpiece relative to the stem may be permitted when manipulating the mouthpiece to either free the apertured end of the metal tube from tightly packed tobacco, or when adjusting the metal tube in the stem'of the bowl to control the smoke passageway between the recess and ported end of said tube. The invention also provides a series of cooling ns on the ferrule to dissipate a large proportion of the heat in the smoke being drawn through'the stem and mouthpiece to thereby in.- sure a cool and enjoyable smoke by the user.

zyw'r-.E Detailed description with a flat, self supporting bottom wall 9 con'-,

tinuous with the stem portion 'I to form a rest so that the pipe may be supported in an upright position when placed upon a surface, such as a table or the like. Formed in the bowl 6 is a tapered bore I which terminates at the :bottom in a floor portion or well I I. The stern 'I is formed integral with the bowl 6 andl is provided with a bore I2 extending laterally from, and communicating with, the tapered bore I0. The free end of the stem 1 isreduced to form a nipple portion I3, and said reduced nippleportion is fitted with a metal sleeve I4 adapted toabe frictionally held inplace, and said sleeve I4 extends from-the shoulder I5 on the stem 'I to the end of the reduced nipple portion I3. An adhesive, or the like, may be insertedbetween the sleeve I4 and nipple I3 or, since the nipple I3 is formed of wood and the sleeve I4 of metal, said sleeve may be tted thereon by a tightpress fit inany suitable well known manner. The surface of the sleeve I4-is machined so as to provide. a substantially true circular surface wall of uniform dimensions throughout its length. Y

The mouthpiece 8 is provided with a bore `I6 extending from the bit portion I1 to the opposite end Where it terminates in an enlarged bore I8 aligned with the bor'l 6. An elongate metal tube I9 has one of its `ends received in said bore I8 so that the bore in the elongate tubular member I9 will align with the bore I6 of the mouthpiece 8.'

The free end of the elongate tubular member I9 is tapered as at 28 and is provided with a central aperture or opening 2I and similarly, a series of apertures 22 are formed on the peripheral portion of the elongate metal tube I9 adjacent the free end thereof so vthat when the tube is projected into the bowl 6 through the bore I2 the apertures 2| and 22 will provide smoke passageways between the tapered bore I0 of the bowl 6 and mouthpiece 8. Formed in the tapered wall I0 of the bowl 6 is a conical recess 23 in diametrically opposed relation to the bore I2 for receiving the tapered end of the elongate metal tube I9, and facilitating the regulation of the aperture 2I by moving the tapered wall 20 toward and away from the recess 23. It is to be noted, that the internal diameter of the bore I2 is slightly llarger than the outer diameter of the elongate metal tube I9 to relieve said stem I of undue stresses and strains imposed by forces accidently exerted on the free end of the mouthpiece 8 and allow` freedom of movement therebetween When the mouthpiece 8 and elongate metal tube I 9 are slid longitudinally back and forth to space the tapered wall 20 the desireddistance from the conical recess 23.

A metal ferrule generally designated by thev reference character 24 is providedwith a reduced |bore 25 adapted to be received on-the metal tube I9 and securely held thereon by being press fit or sweated in place. One end of the ferrule is enlarged as at 2E and is provided with an enlarged bore 2I coextensive with the bore 25, while the opposite end is annularly flanged as at 28 so as to be pressed tightly against the shoulder 29 of the mouthpiece 8. The reduced portion 30 of the ferrule 24, between the enlarged portion 26 and annular flange 28, is provided with a series of circular heat dissipating fins 3| to cool the smoke passing from the bowl I0, elongate metal tube I9 and the area or zone adjacent the inner end of the mouthpieceB,l The cooling tins 3I are formed integral with the reduced portion 30 of the ferrule.

After the metal ferrule 24 is thus iltted and v secured to the elongate metal tube I9, the free by'pressing the same downwardly asusual.

end of the tube is passed through the bore I2 so as to project into the tapered bore I0 in spaced relation to the iloor or well II, with the conical end 20 spaced a sufficient distance from the conical recess 23 to permit the passage of smoke from the bowl to the mouthpiece 8. When the metal tube I9 is thus inserted, the finely machinedfenlarged bore 21 will snugly t upon the sleeve I4l as shown in Figure 3 and thereby establish a substantially rigid joint between the stem I and mouthpiece 8. It is to be understood that the mating surfaces of the sleeve I4 and enlarged bore Z'Iare'machined so as to provide a snug sliding frictional fit in order that the mouthpiece 8 may be partially rotated and thereyby cause partial rotation of the tube I9 so as to shift the apertures 20 relating to the tobacco packed in the vtapered bore I0 of the bowl to free .the apertures 22 from the particles of tobacco Y Operation In use, the parts are assembled as shown vin FIg- `ures l to 3 inclusive and the smoker may flll the tapered bore I0 with tobacco and pack the same After the bore of 'the bowl has thus been filled, the mouthpiece 8 may be turned to the right or left so as to rotate the free end of the metal tube I9 to and fro, and thereby free the apertures 28 of tobacco particles finding their way therein. The tobacco lling in the bowl is then ignited bythe application of a lighted splint or match, and the pipe is smoked by the user in the conventional manner. Should thel smoker desire to increase or decrease the amount of smoke passing through the vtube I9 and mouthpiece 8, he grasps the mouthpiece 8 while holding the bowl in the other yhandland slides the mouthpiece and metal tube inwardly or outwardly with respect to the bowl 8.

During such sliding movement, the nely machined mating surfaces I 4 and 2T of the sleeve and enlargedgbore respectively move relative to one another without destroying the connection between the fer-rule and stem for preventing ,escape of smoke or air therebetween.
